Difference between need and exercise vs create-project in composer

I don't get how a create-project works in composer. Lets take Laravel as
example.I can exercise this PHP horizon with a following command: composer
create-project laravel/laravel --prefer-distThis management installs a
horizon for me withdrawal me with a few folder in a bottom of my
dir:appbootstrappublicvendorPlus some files.But when we simply use a
following composer command:composer need laravel/laravel
--prefer-distcomposer installThen this wholly installs a businessman
folder. No other files and folders are downloaded by composer.How come?
What is so different? How does composer know what other files to get when
we use a create-project laravel/laravel management and since do we wholly
get a businessman folder when we do need laravel/laravel?
